Abstract (en)
A card (1, 301, 401) comprising a card substrate (10, 410); and a light diffraction layer laminated sheet that is laminated on an upper side of the card substrate (10, 410) wherein the light diffraction layer laminated sheet comprises a transparent sheet layer (20, 220, 320); a light diffraction layer (22) configured to have an outer shape smaller than an outer shape of the transparent sheet layer (20, 220, 320) and to be laminated onto an upper side which is one surface side of the transparent sheet layer (20, 220, 320); and a lower adhesive layer (21) that bonds the transparent sheet layer (20, 220, 320) and the light diffraction layer (22) together, characterized in that the transparent sheet layer (20, 220, 320) and the upper side of the card substrate (10, 410) are laminated to each other using thermal welding while being heated and pressurized.
